One of the major milestones of an aviation career is passing your first Part 121 training program. Whether at a regional or national airline, cargo carrier, or major, it is likely to be unlike anything you’ve done before.
For those from a civilian background, Part 121 training will be much more structured and proscribed than Part 61 or even Part 141 certification courses, while also being longer and more in-depth than previous aircraft checkouts. For military aviators, you’ll find airline training to be highly compressed compared to what you’re used to, with lower expectations regarding systems knowledge but a much faster pace of learning.
